Hi, This very small series allows -O3 to be used for all architectures. The first patch marks -O3 as experimental, with the reasoning being that it might expose unwanted regressions to users, and the second patch actually allows -O3 by removing the "depend on ARC" string. The reasoning behind this series is to open up -O3 so that bugs related to it (both compiler-related and kernel-related) can be discovered by eyeballs wanting to improve the "-O3 experience," as that might be beneficial to both compilers and the kernel. This has been attempted before [1], but unfortunately nothing ever came of it.
